What Is Bipolar Disorder?
Bipolar disorder, formerly called manic-depression, is characterized by alternation between two opposite emotional poles: mania, marked by an euphoric, expansive, and hyperactive mood, and depression, dominated by deep sadness that can go as far as suicidal thoughts.
It is estimated that this disorder affects about 1 to 2% of the population, with onset frequently occurring between the ages of 15 and 35, and no notable difference between men and women.
What Is Mania?
A manic episode shows itself through unusual exuberance: the person laughs, sings, talks with everyone, and overflows with energy. However, behind this apparent cheerfulness, excessive irritability is common. Any attempt to limit their excesses or criticize their ideas can provoke intense outbursts of anger. Mania is a pathological state: even if the person seems joyful and full of vitality, their social adjustment is profoundly disrupted.
Symptoms of Bipolar Disorder
People with the disorder move from phases of extremely elevated mood to phases of marked low mood.
-
Manic signs: hyperactivity, elation, feelings of omnipotence, agitation, reduced need for sleep, rapid speech, reckless spending, impulsive sexual behavior, risk-taking, alcohol or drug abuse.
-
Depressive signs: loss of energy, sadness, irritability, loss of self-esteem, suicidal thoughts, appetite disturbances, loss of interest in activities, sleep disturbances.
A manic episode generally lasts at least one week, whereas a depressive episode can persist for several weeks. There are also milder forms of mania, called hypomania, in which mood is elevated without causing a complete breakdown in social or professional functioning.
Possible Causes of Bipolar Disorder
Bipolar disorder results from a complex interaction between several factors:
-
Genetic predisposition: having cases in the family increases the risk, although this does not automatically mean the illness will develop.
-
Neurochemical imbalances: a dysregulation of neurotransmitters such as serotonin, dopamine, or norepinephrine is frequently observed.
-
Environmental and psychosocial factors: major stress, trauma, relationship conflicts, or significant life events (bereavement, separation).
The Different Bipolar Episodes
1. The Manic Episode
Characterized by an excessive elevation of mood, overflowing energy, a reduced need for sleep, racing thoughts, and impulsive behavior. The person may feel invincible and undertake unrealistic projects.
2. The Depressive Episode
Marked by persistent sadness, loss of interest, significant fatigue, sleep and appetite disturbances, difficulty concentrating, and sometimes suicidal thoughts.
3. The Mixed Episode
A simultaneous or rapid combination of manic and depressive symptoms: agitation, insomnia, a flow of rapid thoughts tinged with anxiety, impulsivity combined with deep despair. This type of episode increases the risk of suicide.
Types of Bipolar Disorder
-
Bipolar I: at least one full manic episode (often accompanied by depression).
-
Bipolar II: alternation of major depressive episodes and hypomania (without full mania).
-
Cyclothymia: milder chronic fluctuations lasting at least 2 years, with hypomanic and depressive symptoms insufficient for a full diagnosis.
-
Substance- or medication-induced bipolar disorder: triggered by the use of drugs, alcohol, or certain treatments (e.g., antidepressants, corticosteroids).
-
Bipolar disorder due to a medical condition: for example, thyroid or neurological disorders that can cause mood changes.
Diagnosis
Diagnosis is based on a thorough clinical evaluation conducted by a psychiatrist.
-
Detailed interview (medical and family history, description of episodes).
-
Tracking of mood and sleep changes (logbook).
-
Exclusion of other psychiatric or physical conditions (e.g., thyroid disorders).
Treatment of Bipolar Disorder
1. Treatment of Acute Phases
-
Mood stabilizers (e.g., lithium, anticonvulsants).
-
Atypical antipsychotics (used mainly in severe mania or with psychotic symptoms).
-
Antidepressants (with caution, always combined with a stabilizer to avoid a manic switch).
-
Supportive psychotherapy to help the patient manage their symptoms.
2. Maintenance Treatment
-
Continuation of mood stabilizers over the long term to prevent relapses.
-
Cognitive behavioral therapy (CBT): identifying early warning signs, modifying thought patterns.
-
Interpersonal and social rhythm therapy: regular sleep, management of daily routines.
-
Psychoeducation: informing the patient and their family to improve adherence to treatment.
Aggravating Risk Factors

Chronic stress
-
Lack of sleep

Alcohol or drug use
-
Poor eating habits
-
Social isolation or relationship difficulties
